In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7915: avoid nss underflow in mt7915_mcu_get_sta_nss
If a peer's VHT/HE MCS map has no supported spatial stream (all fields 0x3), the loop exits with nss == 0 and the function returned (u8)-1 (255), which was then written into the firmware sta_rec_bf beamforming fields. Clamp the result to 0.
